Title: Seamless circular knit brassiere and method of making same.
Inventor: OSBORNE HAROLD G
IPC: A41C5/00
Filed: 1998-04-23
Abstract: A seamless brassiere, and methods and blank for making the brassiere are described. In particular, a tubular blank is circularly knit, and first and second walewise extending longitudinal openings are formed along opposite sides of the blank, to form torso and neck openings for the brassiere. The blank ends are trimmed, if desired, to form the desired contour for the arm openings, then banding is applied to each of the torso, neck and arm openings, to thereby form a finished brassiere. At least the banding secured to the torso opening is elastic, in order that the garment may be secured closely about a wearer. In the finished seamless brassiere, the courses extend vertically, while the knit wales extend horizontally when the brassiere is worn, which provides an enhanced level of support for the wearer's breasts.

Patent NL-273426-A (NL)
IPC: B63B27/24
Abstract: 959,493. Pumping systems for liquefied gases. CONCH INTERNATIONAL METHANE Ltd. Dec. 1, 1961 [Jan. 16, 1961], No. 43101/61. Headings F1C, F1G, F1R and F1T. [Also in Division B8] A pumping system for liquids such as liquefied natural gases comprises a turbine 16 driving a pump 10 near the bottom of the liquid container and the working fluid has a solidification temperature below the temperature of the liquid 18 in the container 14. The turbine 16 may be driven by a combination of liquid and gas in which case the turbine exhaust fluid passes through a condenser 40 below the liquid level. After passing through the pump, the pressurised liquid is vaporised in a heat exchanger 50 and led to the turbine in an insulated pipe. If the turbine working fluid has a liquefaction temperature below the temperature of the liquid 18 then the pressurised working fluid passes through a pressure regulator fitted externally of the tank. The working fluid may be the vapour from the liquid in which case it is drawn off from the interior of the container (Fig. 4). Vapour from the container may pass into a separator (Fig. 3 not shown) or directly to the turbine 16 via a compressor 68. The exhaust from the turbine may pass into the line 22 and assist the flow of the effluent from the pump 10 in which case the vapour and liquid pass into the separator, the vapour passing to the compressor or back to the container and the liquid passing to a delivery line. In the event of a pump failure, or to assist the pump, compressed vapour may be passed through the delivery line. This pumping system ensures that vapour is returned to the container to counteract any pressure drop as the liquid level falls. In a modified form of this embodiment, (Fig. 4), the turbine exhaust is led directly to an accumulator 82, which also serves as a separator, and the line 70 has a by-pass 82 leading directly to the delivery line 22 the liquid being pumped direct to a separator 102. When the turbine 16 and pump 10 are inoperative the valve 78 and valves 84, 88 may be opened and liquid is pumped by vapour pressure into the accumulator 82, which has a relief valve 98. The liquid drains through lines 90, 92, 106 to a delivery reservoir.

Abstract: For the winning of hydrocarbons or other materials from underground formations through which a hole has been bored, a gas generator is used. This can be lowered into the borehole to a level in the proximity of the formation to be worked. A fuel and an oxidising agent are delivered to the generator which hasd a pilot stage and a main chamber with an outelt for the passage of the heated gases. In the pilot stage at the upper extremity of the main chamber there is a pilot chamber which is connected to the main chamber by an outlet of limited size. Between the pilot stage and the bottom outlet of the generator, there are a number of separate intermediate stages. A predetermined number of these have outlet nozzles for fuel and oxygen, which are connected to the main chamber. A predetermined number of the intermediate stages also have water nozzlesd connected to the main chamber for the injection of water into it. An end stage is located between the last intermediate stage and the bottom outlet of the generator. This end stage has water nozzles only for injecting into the main chamber. To reduce the viscosity of the oil in the formations and to force it through the wall openings into the borehole for transfer to the surface. Each stage can be regulated selectively and the quantity of energy released by adjusted as required.
